The process may be defined as the physical removal of foreign material, e.g., dust, soil, organic material such as blood, secretions, excretions and microorganisms. Physical cleaning removes rather than kills microorganisms. It is accomplished with water, detergents and mechanical action. In certain settings (e.g., central service or dietetics), the terms decontamination and sanitation may be used for this process.
Soiled or stained stamps are sometimes cleaned with chemicals or by erasing. The cleaning is usually done to improve the appearance of a stamp. A cleaned stamp can also mean one from which a cancellation has been removed, making a used stamp appear unused.
The process of removing scale, oxides, or lubricant--acquired during heating for forging or heat treating--from the surface of the forging. (See also Blasting, Pickling, Tumbling.)
(a) Alkaline cleaning : Cleaning by means of alkaline solutions. (b) Anodic (reverse) cleaning : Electrolytic cleaning in which the work piece is the anode. (c) Cathodic (direct) cleaning : Electrolytic cleaning in which the work piece is the cathode. (d) Diphase cleaning : Cleaning by means of a liquid system that consists of an organic solvent layer and an aqueous layer. Cleaning is effected both by solvent and emulsifying action. (e) Direct cleaning : See cathodic cleaning. (f) Electrolytic cleaning : Cleaning by immersion without the use of current, usually in an alkaline solution. (k) Solvent degreasing : Cleaning by means of organic solvents. (l) Spray cleaning : Cleaning by means of spraying with a cleaning solution. (m) Ultrasonic cleaning : Cleaning by any chemical means aided by ultrasonic vibration. (n) Vapour degreasing : Degreasing by solvent vapours condensing on the work pieces being cleaned.
The removal of soil or unwanted matter from a surface to which it clings.
the removal of visible soil, organic and inorganic contamination from a device or surface, using either the physical action of scrubbing with a surfactant or detergent and water or an energy-based process (e.g., ultrasonic cleaners) with appropriate chemical agents.
The process of removing marks, dust and other contamination and materials from the floor surface.
Physical removal of visible organic material from surfaces.

Cleaning is locating, identifying, containing, removing and disposing of unwanted substances (pollutants) from the environment. It is our most powerful means of managing our immediate surrounding and protecting our health.
Removal of plaque and calculus (tarter) from teeth, generally above the gum line
Also known as clearing, it is the running of a wicket, and therefore removing deadness on all other balls. Having a dirty ball means that the ball may be picked up (ball-in-hand) and actually cleaned upon notification of ones opponents. It is then replaced to its position with no incurred penalty. (exception: see Rover).
A process of removing dirt and reducing the number of micro-organisms from the surface of an object by a process such as washing in detergent
The process of correcting or removing names from a mailing list.
To remove protection from a climb
Refers to removing dirt or otherwise altering the appearance of a coin through the use of chemical or abrasive materials that can damage or scratch the surface in a detectable fashion. Cleaning is different than whizzing or mechanical alteration of the surface. A gentle cleaning in water or solvent that leaves no marks or residue is usually not considered harmful. Cleaning by either mechanical or chemical means that are detectable will generally result in lowering the grade and value of a coin.
Removal of runners, risers, flash, surplus metal and sand from a casting.
To remove aged and discolored varnish; to remove dirt, grime or accretions. NOTE: ALTHOUGH CONSIDERED BY MANY TO BE A BENIGN AND ROUTINE PROCEDURE, CLEANING RANKS AMONG THE MOST DANGEROUS OF PAINTING RESTORATION PROCESSES IN UNSKILLED HANDS (SEE “OVERCLEANINGâ€). Cleaning Examples
